DETAILED DESCRIPTION

In the following description, reference is made to the accompanying drawings which form a part hereof and which illustrate several embodiments. It is understood that other embodiments may be utilized and structural and operational changes may be made.

Failures or problems may occur in a computing environment comprising a plurality of computational devices and other devices. It is desirable to take proactive measures to prevent the failures or problems from occurring.

In certain embodiments, a machine learning module is used to determine proactively the failures and problems that are likely to occur in a computing environment. Measures are taken to prevent such failures and problems from occurring. In certain embodiments, a preemptive system risk identification and reduction mechanism uses a dynamic system scoring in a neural network. The neural network receives multiple inputs relating to the status of system operation and policy, and has an output that uses non-linear weighting of impact values and quantities of devices to generate a risk assessment number. The neural network is trained by actual input values derived from actual incidents that are rated by the type of incident. The neural network may continually be retrained to improve the predictive accuracy of determining the likelihood of failures and problems occurring m the computing environment by using a current state of operational parameters and feedback on actual experienced errors or lack of errors. As a result, improvements are made to the operations of computational devices and other devices to reduce failures and problems within a computing environment.

Exemplary Embodiments

FIG. 1 illustrates a block diagram of a computing environment 100 comprising a computational device 102 in which a preemptive failure management application 104 and a machine learning module 106 are implemented, in accordance with certain embodiments.

The computational device 102 is configured to receive data related to the operations of host computing devices 108, storage controllers 110, and storage devices 112 that are present in the computing environment 100. The storage controllers 110 allow the one or more hosts computing devices 108 to perform input/output (I/O) operations with logical storage maintained by the storage controllers 110. The physical storage corresponding to the logical storage may be found in one or more of the storage devices 112 and/or a cache of the storage controllers 110.

The computational device 102, the storage controllers 110 and the host computational devices 108 may comprise any suitable computational device including those presently known in the art, such as, a personal computer, a workstation, a server, a mainframe, a hand held computer, a palm top computer, a telephony device, a network appliance, a blade computer, a processing device, a controller, etc.

The computational device 102, the storage controllers 110 and the host computational devices 108 may be elements in any suitable network, such as, a storage area network, a wide area network, the Internet, an intranet. In certain embodiments, computational device 102, the storage controllers 110 and the host computational devices 108 may be elements in a cloud computing environment.

The plurality of storage devices 112 may be comprised of any storage devices known in the art, such as solid state drives (SSD), hard disk drives (HDD), etc.

In certain embodiments, the preemptive failure management application 104 and the machine learning module 106 may be implemented in software, hardware, firmware or any combination thereof. The preemptive failure management application 104 uses the machine learning module 106 to determine the likelihood of failures and problems occurring in the host computational devices 108, storage controllers 110, and storage devices 112 of the computing environment 100 and sends indications for taking preventative measure to prevent such failures and problems.

In certain embodiments, the machine learning module 106 may implement a machine learning technique such as decision tree learning, association rule learning, neural network, inductive programming logic, support vector machines, Bayesian models, etc. In certain embodiments, the machine learning module 106 is a neural network.

Therefore, FIG. 1 illustrates certain embodiments in which a machine learning module 106 is used by a preemptive failure management application 104 to determine the likelihood of failures and problems occurring in the computing environment 100.

FIG. 2 illustrates a block diagram 200 that shows a mechanism for detecting the likelihood of failure of a computational system via the preemptive failure management application 104 and a machine learning module 106 comprising a neural network 202, in accordance with certain embodiments.

The neural network 202 may comprise a collection of nodes with links connecting them, where the links are referred to as connections. For example, FIG. 2 shows a node 204 connected by a connection 208 to the node 206. The collection of nodes may be organized into three main parts: an input layer 210, one or more hidden layers, 212 and an output layer 214.

The connection between one node and another is represented by a number called a weight, where the weight may be either positive (if one node excites another) or negative (if one node suppresses or inhibits another). Training the neural network 202 entails calibrating the weights in the neural network 202 via mechanisms referred to as forward propagation 216 and back propagation 222. Bias nodes that are not connected to any previous layer may also be maintained in the neural network 202. A bias is an extra input of 1 with a weight attached to it for a node.

In forward propagation 216, a set of weights are applied to the input data 218, 220 to calculate an output 224. For the first forward propagation, the set of weights are selected randomly. In back propagation 222 a measurement is made the margin of error of the output 224 and the weights are adjusted to decrease the error. Back propagation 222 compares the output that the neural network 202 produces with the output that the neural network 202 was meant to produce, and uses the difference between them to modify the weights of the connections between the nodes of the neural network 202, starting from the output layer 214 through the hidden layers 212 to the input layer 210, i.e., going backward in the neural network. 202. In time, back propagation 222 causes the neural network 202 to learn, reducing the difference between actual and intended output to the point where the two exactly coincide. Thus, the neural network 202 is configured to repeat both forward and back propagation until the weights (and potentially the biases) of the neural network 202 are calibrated to accurately predict an output.

In certain embodiments, the plurality of inputs 218, 220 comprise a plurality of states of components of the computing environment 100. The output 224 may represent a risk score that provides a failure likelihood comprising the risk of failures and other problems in the computing environment 100.

FIG. 3 illustrates a block diagram that shows exemplar) inputs to the machine learning module comprising the neural network 106, in accordance with certain embodiments.

In certain embodiments an input to the neural network is a measure of a firmware or software level of a device (e.g., the devices 108, 110, 112) in comparison to a minimum or recommended firmware or software level for the device (as shown via reference numerals 302, 304). If the firmware or software level of the device is not at the recommended firmware level of the device or at least at the minimum firmware or software level of the device, then there is potential for failures or problems caused by the firmware or software level of the device. For example, if a device is many levels below the recommended or minimum firmware or software level then there may be a high likelihood for failures or problems caused by the device, and if a device is just one level below the recommended or minimum firmware or software level then there may be a small likelihood for failures or problems caused by the device.

In certain embodiments, the inputs are indicative of whether a device has reached an end of life cycle (as shown via reference numeral 306). For example, is a device has an end of life cycle of two years, then after two years of usage, the device is likely to be a cause of failure or problems.

In certain embodiments, the inputs are indicative of a ratio of faulty replaced drives to total number of drives over a period of time (as shown via reference numeral 308). The higher the ratio the higher may be the rate of failures and problems in the computing environment 100.

In certain embodiments, the inputs are indicative of a level of redundancy in the computing environment indicated by Redundant Array of Independent Disks (RAID) configurations (as shown via reference numeral 310). The less redundancy a RAID level provides, the more likely the loss of data, whereas the more redundancy a RAID level provides the more computations need to be performed for storing data.

In certain embodiments, the inputs are indicative of whether critical policy failures have occurred in the computing environment (as shown via reference numeral 312), number of devices that have missed heartbeats (as shown via reference numeral 314), an age of device (as shown via reference numeral 316), and number of problematical devices identified by service personnel (as shown via reference numeral 318). The inputs may also be indicative of devices that have high impact issues that may lead to a severe error condition to occur (as shown via reference numeral 320).

It should be noted that inputs shown in FIG. 3 are exemplary, and many additional types of inputs may be applied to the machine learning module comprising a neural network 106.

FIG. 4 illustrates flowchart 400 that shows operations of the machine learning module 106, in accordance with certain embodiments.

Control starts at block 402 in which the preemptive failure management application 104 initially assigns weights and biases in the machine learning module 106 based on estimates. A determination is made at block 404 as to whether a customer issue (i.e., a problem or failure in the computing environment 100 that affects a customer) has occurred. If so (“Yes” branch 406), control proceeds to block 406 in which weights and biases are adjusted in the machine learning module 106. This is referred to as training the machine learning module 408 by adjustment of weights and biases so that learning occurs from the identified customer issue.

If at block 404 a determination is made that a customer issue has not occurred (“No” branch 410) then control returns to block 404.

FIG. 5 illustrates a block diagram 500 that shows how the expected output for the machine learning module is computed, in accordance with certain embodiments. The expected output is a risk score where if the severity of a failure or problem is high than the risk score is high, and if the severity of a failure or problem is low then the risk score is low (as shown via reference numeral 518).

In case of a data loss or data integrity loss, a risk score of 100 is provided (as shown via reference numerals 502, 510). In case of a loss of access for a long period of time such as over 30 minutes, a risk score of 80 is expected (as shown via reference numerals 504, 512). In case of a data loss of access for a short period of time such as 30 minutes or less, a risk score of 60 is expected (as shown via reference numerals 506, 514). In case of a performance impact, a risk score of 40 is expected (as shown via reference numerals 508, 516).

The risk scores 510, 510 512, 514 comprise expected outputs of the machine learning module 106 in response to certain failures or problems. The expected output is used to compute a margin of error from a risk score computed in the machine learning module 106, to train the machine learning module.

FIG. 6 illustrates a flowchart 600 that shows how the weights and biases of the machine learning module 106 are adjusted, in accordance with certain embodiments.

Control starts at block 602 in which an expected risk score is computed. A determination is made of input values for an impacted device (at block 604) and a risk score calculated using forward propagation in the machine learning module 106 (at block 606). Then the calculated risk scored is compared to the expected risk score, and the margin of error that is determined is used to adjust the weights and biases of the machine learning module 106 via back propagation (at block 608). As a result, the machine learning module 106 learns to improve its operation and calculate superior outputs in the future.

FIG. 7 illustrates a block diagram 700 that shows how alerts are sent based on the output of the machine learning module 106, in accordance with certain embodiments.

After undergoing some training, the machine learning module 106 is set to a mode in which alerts may be generated. In such a mode, the output (i.e., the calculated risk score) of the machine learning module 106 is analyzed by the preemptive failure management application 104. If the output is below 20, then the preemptive failure management application 104 determines that there is a low risk of failure or other problems (reference numeral 702). If the output is between 20 and 40, then the preemptive failure management application 104 determines that there is a medium risk of failure or other problems (reference numeral 704). If the output is between 40 and 60, then the preemptive failure management application 104 determines that there is a high risk of failure or other problems (reference numeral 706). If the output is above 60, then the preemptive failure management application 104 determines that there is a critical risk of failure or other problems (reference numeral 710). If there is a high risk or critical risk of failure or other problems than an alert is sent by the preemptive failure management application 104 to the customer (as shown via reference numeral 712).

FIG. 8 illustrates a flowchart 800 for using the machine learning module 106 to perform preemptive identification and reduction of risk of failure in computational systems, in accordance with certain embodiments. In certain embodiments, the operations shown in FIG. 8 may be implemented in the computational device 102.

Control starts at block 802 in which input on a plurality of attributes of a computing environment is provided to a machine learning module 106 to produce an output value that comprises a risk score that indicates a likelihood of a potential malfunctioning occurring within the computing environment 100. A determination is made (at block 804) as to whether the risk score exceeds a predetermined threshold. In response to determining that the risk score exceeds a predetermined threshold, an indication is transmitted (at block 806) to indicate that potential malfunctioning is likely to occur within the computing environment 100. A modification (at block 808) is made to the computing environment to prevent the potential malfunctioning from occurring. For example, the modifications may include updating the firmware of a devices whose firmware is not at the recommended level.

Therefore, FIGS. 1-8 illustrate certain embodiments, in which a machine learning module 106 is used to predict the likelihood of failures or problems in a computing environment, and take appropriate actions prior to the occurrence of the failures or problems.

Further Details on Exemplary Inputs

In certain embodiments, the following exemplary inputs may be used as inputs to the machine learning module 106 for identifying risks in a system, where each exemplary input may have an associated weight that may be dynamically altered by using back propagation mechanisms (some of these inputs may have been described earlier in FIG. 3 with a different nomenclature):

(1) Firmware Currency Analysis based input: This is reflective of a process of tagging a device in case it is not running on a recommended firmware level, because running on a not recommended firmware level is a major cause of device failure.

(2) End of Life/End of Service (EOL/EOS) based input: The system flags a device if it has approached EOL/EOS date.

(3) N/(N−1) Analysis based input: This is based on how many hops a device current firmware level is behind the recommended level (The older the firmware level more the more vulnerable the device is likely to be).

(4) Storage Automation Tool (SAT) Policy Failure based input: A storage automation tool has the capability to check the status of health check policies on a given device. Devices having fatal and/or critical failures may result in outage and may need to be addressed immediately. (5) Disk Currency based inputs: This is reflective of a process of flagging a drive in case it is not running at a recommended level (A drive running at outdated firmware level is more likely to cause a disk crash). (6) Missed Heartbeat or no heartbeat based inputs: In case a device is not calling in periodically to indicate an operational status, a home system may not be able to get the current machine configuration and this may result in problems. (7) Device Age based inputs: The older the device, the higher the risk of failure. (8) Problematic Drive determination based inputs: Drive vintage is determined based on number of returned drives within the last 12 months. The identification of bad drives in an asset and quick replacement of such drives is a key measure in outage avoidance. (9) Ratio of Faulty Drive based inputs: This is the ratio of the total number of faulty drives replaced to the total number of drives over a period of time. The higher the replacement rate, the more the vulnerable a device is to failure. (10) RAID5 Identification based inputs: RAID5 configuration may result in irreversible data loss in case of double disk failures. This process highlights assets running on RAID5 configuration proactively and may greatly reduce risk of an outage. (11) Historical Incident based inputs: If a device had an outage in the past, then the risk of failing again is greatly increased, and historical data is used to find a registered outage. (12) High Impact Known Issues based inputs: High Impact issues that a computational device is exposed are used as inputs.

The above inputs may be grouped into two broad classes:

1. Inputs based on device level predictors: e.g., Firmware level, End of Life or End of Service, Policies, (N/N−1) Analysis, Missing heartbeat, Historical incidents, High impact known issues, device age, etc. as described above; and

2. Inputs based on component level predictors: e.g., Disk Firmware currency, problematic drives, ratio of faulty drives, drive age, RAID5, etc. as described above.

It should be noted that in alternative embodiments, many other inputs may also be used.
